Does anyone else find that with IBS you always have to have a full stomach, or the next time you eat you'll get sick? It's driving me crazy. I'm a small girl and I don't weigh much, but with a fast metabolism and the knowledge that if I eat once I'm already hungry I'll be very uncomfortable, I'm constantly eating. I've gained 10 pounds since the diagnosis and I know I'm not fat, but it still really bothers me. I don't know if there's a way to get around this, or a food that I can eat to make it better. I always eat really healthy food, but still it makes me feel gross. Does this happen to other people?
